5 And this is the declaration which we have heard from him, and declare unto you: That God is light, and in him there is no darkness.6 If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth. 7 But if we walk in the light, as he also is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin. 8 If we say that we have no sin, we deceive ourselves, and the truth is not in us. 9 If we confess our sins, he is faithful and just, to forgive us our sins, and to cleanse us from all iniquity. 10 If we say that we have not sinned, we make him a liar, and his word is not in us.

1 My little children, these things I write to you, that you may not sin. But if any man sin, we have an advocate with the Father, Jesus Christ the just: 2 And he is the propitiation for our sins: and not for ours only, but also for those of the whole world.
